PPD for the 5000 series Radeon cards???

batmeat

Everyone knows that F@H clients work exceptionally well on Nvidia boards, but how does the new 5870/5850 card fair? My GTX 260 puts out around 7200 ppd, my 4870 (when I had it) could barely pump out 3000 to give you an idea. I'd love to crossfire a pair of 5870's but not if I can get more points/wu's done from a single gtx 285.....well?

In case any are wondering, I did some more digging and found that folding still sucks on ATI cards. Don't expect anything till client 6.24 comes, and even then it's iffy if OPEN CL will be supported which supposedly will boost PPD on ATI cards. Seeing how the 4000 series cards were out over a year ago, you can imagine if or when any update will come from Stanford.

kwak

as far as i can tell, folding doesnt work yet on the 5000 series.
but im not expecting any huge improvements except for the normal one you get with more shaders. the lower ppd is probably due to the difference in architecture.

U can use switch to make program to think that u run r700 chip which is supported -forcegpu ati_r700
My 5870 at 1GHz get ~5,5k PPD

XD thanks for that!

[EDIT] Are you using two clients? Which drivers are you using?

I'm getting unstable machine errors

Hopefully it's just the 9.11 betas and I haven't got a damaged card, but with all the bad luck I've had recently I wouldn't rule it out.

Using 9,11 beta. Also running 2x CPU Client. And I'm too getting error while trying to do something for example on full screen, like watch movie or play something, even screen saver cause folding to crash on GPU. Have no problems while playing music or browse Internet.

Cheers for the info, I'm starting to wonder if there's an underlying problem with all 5xxx GPUs. I've been getting white dots in Crysis, but looking at their forums it's a known issue. Other people get artifacts in Vantage, apparently another known issue. I have my doubts drivers are going to fix these problems.

[EDIT] I rolled back to these drivers and it seems to be folding without errors now. PPD sucks at 4000, but it's better than nothing.

My 4850 was getting 4500PPD....as per fahmon. My GTX275 gets roughly 7500PPD....until F@H crashes..

Think F@H is what actually did in my 4850....lol.

I'm getting PPD of 2421.72 running Folding@Home at 96% (no clue y it ain't hitting higher, probably because the system is loaded in other things).

There has to be some issue with the drivers....HD5870 shouldn't be getting less PPD than an HD4850 did. If ATI can get that resolved, I'll reconsider buying one for folding.

thought i would load it back up after over a year...

damn!!!!!!!
folding on both of my 4870x2 gpus and also smp cpu client gives me about 4800ppd
loaded just the gpu core client on my sons 8800gtx and 5600ppd lol

ATI sucks at folding big time.

sykozis · 11-07-2009, 11:22 | posts: 3,338 | Location: USA | User is Offline

My HD4850, OC'd to 700/1105 managed to pull off 4500PPD...4200PPD at stock clocks...my GTX275 gets 7500PPD.

There has to be some issue with the 6.23 client that's dropping everyone's PPD....I refuse to reinstall my 4850, as I currently have my system stable again.

They seriously need to redesign the F@H client to work better with ATI GPU, im sure it's not being used to its full potential.

I might be wrong here but i have read somewhere that the current client was originally designed for the HD3000 series cards and never updated to optimize the HD4000 fully, however there was an update just to support the card. Same for the HD5000 series, you can trick F@H to think you have got an HD4000 series card but that wont help you much since the program is not optimized for the new hardware. Kinda sad.

ATM im using my cpu to fold since i can't study for my exams with 2 HD4850 card's fan at 100%, sounds like if there is an leaf blower on in my room.

EDIT: btw i can only get 2k PPD out of one HD4850 at stock speeds, is this normal? Im using CCC 9.8.

I've given up trying to fold with this card, I'm still getting errors. Until a new client and drivers are released with better support I don't think I'll bother as only one out of about every 10 work packets completes successfully.

Not sure who's is normal....or if the "estimates" are even close to accurate...

I'm having problems with Vista, any ideas?

We have seen reports that the GPU client only works well in Vista when running in "XP Compatibility Mode" or to "run as Admin." We suggest trying this out if you are having problems with the ATI client in Vista. We are investigating work arounds.

Also it is noted the way ATI works they drop 50% of each cycle due to double precision. ATI uses double precision vs Nvidia's single, current. Also reading the new NVidia Fermi will be using double precision. If that is only option like ATI it may see the same issue. But till them cards get out that is only speculation. This could be reason it has so many additional shaders.

To compare
280 GTX
240 shader cores

vs

Fermi (from specs released by Nvidia)
512 shader cores

I have noticed my core on the HD4850 is not getting very hot, when i play games it pumps out alot more heat than when im folding. This just gives me the idea the card isn't being really used to its full potential.

Actually, F@H-GPU was originally designed for the HD2000 series and updated for HD3000 and HD4000 (for compatibility). F@H-GPU still follows the shader count used in the HD3000 series.

Mine, with stock cooler, rarely got above 85C...but would reach 105C running WoW. F@H, at current, isn't designed to use all available shaders on HD4000 or HD5000 series cards.

F@H uses CUDA for nVidia GPU's, so they're likely to see less of a performance impact than ATI users get. If F@H were to use AMD Stream for the HD4000 and HD5000 series, I'm sure they'd see a performance improvement as AMD Stream was designed for RV6xx, RV7xx and RV8xx....so it should be able to use the proper shader count.

One can only hope that client 6.24 will change all that.

Sigh im getting alot of BSOD when i fold on my gpu in win7, using driver 9.11 beta but this has also happened in 9.9 and 9.10. Ill just fold on my cpu for now, cant really debug the issue now.

I have not used win7 yet but try the idea from folding help and put in xp compatible mode like with Vista.

It is not just ATI that is not completing folds. My Nvidia has failing at

90% but get credit for the 90% that is uploaded. Ones I am failing are the new ones so, more than likely, something is wrong with them.

Zebatshu · 11-10-2009, 20:34 | posts: 97 | Location: South Africa | User is Offline

Ill try that once im finished with my exams, im right in the middle of it now, so cant really waist time to debug this issue.

sardine · *Last edited by sardine; 11-11-2009 at 11:32.*

folding for 3-4 days now on Windows 7 x64 Retail boxed (yup i got it for my birthday

) and no problems appart from every now and then a 5-10 sec pc freeze (mouse pointer still moving)

just folding on gpu2 and disabling gpu1 stops the random freezing..

sad really when im folding on my 4870x2 ati gpu2 2023ppd and my sons 8800gtx 5258ppd

im half and half about ati stream update for f@h as if they do use the ATI stream efficiently then that creates more heat and hard work the reason for my 280gtx failures 100% usage 24/7 killed them both and a 1kw thermaltake psu..

I only get 2923PPD on my OC'ed 4890. Not sure why it is so low but thats what FaHMON is telling me.

chanw4 · 11-18-2009, 05:27 | posts: 625 | Location: Hong Kong | User is Offline

according to FAHMON, I'm getting ~2 - 2.1k PPD but the GPU is running @ ~ 40-50% only.
